摘　　要：泵阀作为隔膜泵的重要组成部分,卡阀故障时有发生,给生产带来了很大损失。本文采用小波包频带分解技术,有效提取了泵阀的卡阀故障。这项技术应用在大型隔膜泵上,具有一定的经济意义。The valve is of the most important portion of a reciprocating diaphragm pump. Valveblocked fault is happened commonly and affects production. Frequency band energy decomposition with wavelet packet can identify effectively the characteristics of valve-blocked fault and diagnosis fault by using vibration signals. The application of this technique to large-sized reciprocating diaphragm pumps will makes more benefit to users.
